OIL BURNER.

Application filed March 15, 1921. Serial No. 452,517.

1/ 0 all whom it may concern: I p Be it known that we, VERNON W. RUSS LLand Jnssn T. KYLE, citizens of the United States, and residents of Brea,county of Orange, and State of California, and JULIAN A. CABIPBELL, acitizen of the United-States, residing at Long Beach, in the county ofLos Angeles and State of California, have invented new and usefulImprovements in :0 Oil Burners, of which the following is aspecification.

It is the Object of this invention to, pr-l lar narrow elongated port soas to obtain the desired pressure. I

The invention will be readily understood from the following descriptionof the accompanying drawings, in which- Figure 1 is a longitudinalsection through a burner constructed in accordance with the invention.

Fig. 2 is a detail section on the line 22 of Fig. 1.

Figs. 3 and 4 are transverse sections on the lines 3 3 and 44e of Fig.1.

The fuel chamber of the burner is shown at 1 as of relatively largediameter at its rear end, as shown at 2, and tapering to a relativelysmall diameter atits forward end as shown at 3. An end plate 4 isretained against the open rear end of the burner chamber as by a closureplate 5 threaded onto the end of the burner. chamber and provided Withthe shoulder 6 engaging a shoulder 7 upon plate 4: for retaining thelatter in position. The closure plate 5 is provided with an axialopening and is connected to a conduit 8 as by a suit-able threadedconnection. A second conduit 9 extends through conduit 8 and through anaxial opening 10 in plate 4 so that the inner conduit discharges intothe fuel chamber The mixed fuel and mixed fuel, steam and air escapes,is a simi- I beyond the plate 1. The conduit 9 be held in position withrelation to plate 4 by means of a nut 11.

A T-joint 12 is preferably arranged upon conduit 8 with conduit};extending rearwardly beyond the same as through a pipe 18 provided inthe end of the T-joint. A pipe let'isconnected to the angularly disposednipple of the T-joint, said pipe being provided with a suitable valve15, and a Valve 16 is arranged in the rearwardly extending portion ofconduit 9. The conduit 9 ISCOIIIlQCtGCi to a suitable fuel supply,

while the pipe 1 1 is connected to a steam' supply in order that steammay be dis charged through conduit 8 into a space 17 between plate 4 andthe closure cap 5.

A. concave baffle plate 18 is arranged in fuel chamber 1 over thedischarge end of conduit 9, said baffle plate being preferably held inposition by screws 19 received through the same and into plate 4. Theaxial, portion of the baflie plate is spaced somewhat beyond the end ofconduit 9,, and the radially extending arms 20 of thebaflie plate curvetoward plate 41- with the ends of said. arms forming restricteddischarge passages 21 between the baflie plateand plate 4 adjacent thewall of chamber 1. The

arms 20- are so arrangedthat the discharge.

ports 21 extend in opposite directions and are adaptedto discharge fuelfrom the same circumferentially of fuel chamber 1. By this arrangementit willbe seen that the fuelasv discharged to the fuel chamber isprovided with a whirling motion as it travels axially of the fuelchamber. 7

- The plate a is provided with discharge ports 22 communicating with thespace 17 I and tapering to restricted discharge ends 23 opening into thefuel chamber 1 adjacent the discharge port 21 provided by baffle 18. Theports 22 are inclined, as clearly shown in Fig. 2, with the dischargeends 23 thereof extending circumferentially of plate 1 and in thedirection of discharge through the respective ports 21, so that thesteam discharged through ports 22 will also be provided with a whirlingmotion within the fuel chamber. By this arrangement it will be seen thatthe fuel and steam will be thoroughly mixed during their passage throughthe fuel chamber.

A burner head 25 is connected to discharge end 3 of the fuel chamber bycoupling 26,

and said burner head tapers outwardly somewhat towards its discharge end27. The discharge end of the burner head is arranged as a relativelynarrow elongated port, as clearly shown in Fig. 4. An air conduit 28surrounds the burner head and the discharge end 3 of the fuel chamber inspaced relation therefrom and is preferably supported by a" spider 30.The ends of conduit 28 are open so as to form an annular air passageway31 surrounding the burner head, and the respective ends of the'airconduit flare outwardiy with the front end extending beyond thedischarge port 27 of the burner head and forming a discharge port 32 forthe mixed fuel, steam and air. This discharge port is also arranged as arelatively narrow elon-- I gated opening, as clearly shown in Fig. i.

' duits and arranged to cause whirling dis-' The device as thusdescribed provides for the efficient mixture of steam and fuel in thefuelchamber of a. burner, by setting up a whirling motion of the mixedfuel and steam, and the restricted discharge ports provided fortheburner head and'for the air conduit, form means whereby the'mixed fueland steam after mixture with air in order to form a combustible product,will be discharged at high velocity through the burner.

Various changes may be made without departing from the spirit of theinvention as claimed.

What is claimed is: c

1. A burner comprising a fuel chamber, a fuel supply conduit, a separatesupply conduit for another fluid, and a fixed baifle in said chamberover said supply conduits, said baffle having a concave lower surfaceand being spaced beyond the ends of said concharge of saidfu'el to saidchamber.

2. A burner comprising a fuel chamber, a fuel supply conduit, a separatesupply con duit for another fluid, a fixed bafiie in'said chamber oversaid supply conduits, said loaf fie having a concavelower'surface andbelng spaced beyond the ends of SZtId'COHdlll'tS and arran ed to causewhirling discharge of said fuel to said chamber, and means for mixing afluid with said fuel as it is discharged to said chamber.

3. A burner comprislng a fuel chamber, a

' fuel supply conduit, a separate supply conduit foranother fluid, afluid supply'conduit,

a fixed baflie in said chamberover said fuel 7 supply conduits, saidbaflle having a concave lower surface and being spacedbeyond the ends ofsaid conduits and arranged to cause whirling discharge of said fuel'tosaidcham- Iber, and a discharge for said fluid supply to said chamberatthe discharge edge of said baflie;

4. In a burner, a mixing chamber, a partition arranged in one endthereof, which partition is provided with an inclined steam jet, openingmeans for supplying'steam to the chamber behind-said partition, a fixedbafiie plate arranged in front of said partition and provided'with anozzle that is arranged to discharge circumferentially relative to thewalls ofthe fuel chamber, the open end of said nozzle terminatingadjacent to the steam jet opening through the partition,and

means for supplying liquid. hydrocarbon to steam jet opening through thepartition,

means for supplying liquid'hydrocarbon to the chamber'between saidpartition and said bafiie, said fuel chamber being provided with a fueloutlet and an air tube surrounding said fuel outlet.

6. A burner comprising a fuel chamber, a fuel supply conduit, a fluidsupply conduit, a fixed concave baflie in said chamber over said fuelsupply conduit and arranged to cause whirling-discharge of said fuel tosaid chamber, and a discharge for said fluid supply" to said chamber atthe discharge edge of said 'bafiie andarranged to cause whirlingdischarge of said fluid.

In testimony whereof wehave signed our names to this specification.
